CPC G05D 1/0278 (2013.01) [G05D 1/0221 (2013.01); G05D 1/0223 (2013.01); H04W 4/44 (2018.02)] | 5 Claims |
1. A system for multi-range vehicle speed prediction along a travel corridor having a plurality of intersections for enhanced energy management of a vehicle, the system comprising:
a data-driven prediction module configured to receive historic traffic data from at least one of GPS, a connected vehicle database, and traffic signal timing data along the travel corridor for long-term vehicle speed prediction, organize the historic traffic data into a plurality of bins, and determine and output long-range speed predictions;
a model-based speed prediction and planning module configured to receive real-time traffic data including connected vehicle data and traffic signal timing and phasing data, estimate queuing dynamics at signalized intersections along the travel corridor using a shockwave profile model to estimate a queue length at each of the plurality of intersections for eco-trajectory planning, and output a short-range speed prediction;
an integration module configured to integrate the short-range and long-range speed predictions to output a multi-range speed forecast; and
a control module configured to solve a real-time optimization to minimize energy consumption of the vehicle while simultaneously enforcing power and thermal system constraints and output a model predictive control (MPC) signal to the vehicle and associated control actions in response to the multi-range speed forecast for predictive controlling of an operation of the vehicle power and thermal systems.
